ADVICE:
When you see someone truly broken up, shattered & scattered all over, don't pity him for pity is for the weak. He needs not your sympathy for sympathy is for the sick. He require not your condolences for condolences are for the dead.
Instead just calmly help pick up the pieces & put them together, with him. This act of yours will not determine whether he lives or dies but will determine whether he becomes BITTER or BETTER.
Trust me, I've been there & the pain itself doesn't hurt as much as the understanding people...simply not understanding.
